I've just spent the last hour-and-a-half researching wedding shit for a scene I'm writing, and I can think of only two words: fucking paininthearse.
If I ever have the misfortune to have someone I actually love pop the question, the first thing I'll ask before even considering saying yes is, "Are you good with eloping?" If the answer is yes, then my answer might be yes. It depends on whether ye olde significant other plans to have a big reception later on or not. If not, then all is well.
This is some crazy shit we engage in when it comes to signing a few documents saying you're not longer a Miss.
